L-T Isolation Transformer


Isolation transformers are a type of transformer, designed to have primary input and secondary output windings. Both these windings are separated with the help of an electric insulation barrier. Therefore, in case of any fault, the power is not transferred to next stage. Isolation Transformer converts or transformers the current or AC voltage from one level to another level. It does it's the principle of isolating different sections of electrical systems to stop current flow. The transformer transfers electrical power from a source of alternating current energy to a device. To ensure safety measure, the powered device is isolated from the power source.

Linear Servo Voltage Regulator (Roller Type)

Linear Voltage Regulator

Linear Voltage regulators employ vertical windings with Carbon Rollers on both sides of the coil. Linear technology employs heavy section of electrolytic grade rectangular Copper Strip, in order to minimize the losses. The core is built from grain oriented silicon steel laminations to keep the losses to the minimum. This is suitable for 100% continuous duty & have the capability to adhere to heavy inrush starting Loads.

Roller Carbon Brush

The Roller brush technology gives high reliability due to less wear & tear, as the surface area in contact keeps on changing during the stabilization process. The roller contact is fitted with spring tension behind to keep the roller intact with coil for trouble free operation. There are self lubricationg roller assemblies with a life span of appx. 1 lac track meters.
